•
Derivative Time:
Allows you to define the derivative time. It refers to the
D
value of the PID control mode, in seconds. Available only when
the
Proportional Band
parameter is
0. Range: 0 ~ 300,0 (in seconds).
•
Control cycle action period:
Allows you to define the PWM cycle value. Available only when the
Proportional Band
parameter is
0. Range: 0,5 ~ 100,0 (in seconds).
•
Control Action:
Allows you to enable the control logic to be used: “Heating (Reverse)”, which turns on the control output when the
PV is below SP,
or “Cooling (Direct)”, which turns on the control output when the PV is above SP. Only available for “Automatic”
control mode.
•
Control Hysteresis:
Allows you to define a hysteresis value for ON/OFF control mode (To define an ON/OFF control mode, the
Proportional Band
parameter of the Tuning tab must be set to 0.0). Adjustable between 0 and the measurement range width of the
selected input type.
•
Lower limit of SP:
Allows you to define the lower limit for the Setpoint adjustment. Allows you to define the minimum value of the
PV indication range and limit the SP adjustment of the available
linear analog signal inputs
(0-20 mA, 4-20 mA, 0-50 mV, 0-5 V
and 0-10 V).
•
Upper limit of SP:
Allows you to define the upper limit for the Setpoint adjustment. Allows you to define the maximum value of the
PV indication range and limit the SP adjustment of the available
linear analog signal inputs
(0-20 mA, 4-20 mA, 0-50 mV, 0-5 V
and 0-10 V).
•
Control output value in case of sensor error:
Allows you to define a specific value for the control output in case of sensor error.

Alarm 2 Function:
Allows you to define alarm 2 function: “Off”, “Minimum”, “Maximum”, “Differential”, “Minimum Differential”,
“Maximum Differential”, “Open Sensor”, “Ramps and Soaks Event”, “End of Soak” or “Open Loop” (see
section).
•
Alarm 3 Function:
Allows you to define alarm 3 function:
“Off”, “Minimum”, “Maximum”, “Differential”, “Minimum Differential”,
“Maximum Differential”, “Open Sensor”, “Ramps and Soaks Event”, “End of Soak” or “Open Loop” (see
section).
•
Alarm 4 Function:
Allows you
to define alarm 4 function: “Off”, “Minimum”, “Maximum”, “Differential”, “Minimum Differential”,
“Maximum Differential”, “Open Sensor”, “Ramps and Soaks Event”, “End of Soak” or “Open Loop” (see
section).
PARAMETERS OF EACH ALARM:
Each type of alarm has specific parameters. The sections below present the configuration parameters for Alarm 1 function modes, but all
alarms have the same parameters.
MINIMUM ALARM
•
Alarm 1 SP:
Allows you to define the trigger point for Alarm 1. Range: According to the minimum and maximum SP limits configured.
•
Alarm 1 Initial Blocking:
Allows you to define whether there will be an initial block of alarm 1 (see
section).
•
Alarm 1 Hysteresis:
Allows you to define a hysteresis value for Alarm 1.
•
T1 of Alarm 1:
Allows you to define a timer interval for the activation of Alarm 1. Range: 0 ~ 5999 (in seconds).
•
T2 of Alarm 1:
Allows you to define a second timer interval for the activation of Alarm 1. Range: 0 ~ 5999 (in seconds).
•
Displays SPA1 in the Operation Cycle:
Allows you to define whether the SPA1 of Alarm 1 will be displayed in the Operation Cycle of the
device.
•
Flash in Alarm 1:
Allows you to define whether Alarm 1 will display an alert flag on the display when it is in an alarm situation (see
section).
